2.CHECK BATTERY SMART UNIT

  1. Ensure the safety of the areas in front and at the back of the vehicle.

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch on (READY).

  1. Enter the following menus: Powertrain / Hybrid Control / Data List / Batt block Vol -V01 to V14.

  1. Fully warm up the engine and turn the air conditioning off.

  1. Firmly depress the brake pedal with your left foot.

  1. Move the select lever to D.

  1. Record each battery block voltage from the data list (Batt block Vol -V01 to V14) while fully depressing the accelerator pedal.

  1. Compare the battery block voltages (VB0 to 13 Batt block) between the even and odd number groups in each combination shown in the table below.


Even Number Group
Odd Number Group
Battery Block Voltages to be Compared
V0 BATT BLOCK
V1 BATT BLOCK
VB0 - VB1
V2 BATT BLOCK
V3 BATT BLOCK
VB2 - VB3
V4 BATT BLOCK
V5 BATT BLOCK
VB4 - VB5
V6 BATT BLOCK
V7 BATT BLOCK
VB6 - VB7
V8 BATT BLOCK
V9 BATT BLOCK
VB8 - VB9
V10 BATT BLOCK
V11 BATT BLOCK
VB10 - VB11
V12 BATT BLOCK
V13 BATT BLOCK
VB12 - VB13

  1. Check the difference in voltage of each combination.

Result:
Result
Proceed to
Difference in voltage of each combination is 0.3 V or higher.
A
Other than above.
B

HINT:
If the difference in voltage of each combination is 0.3 V or higher, it is due to a battery smart unit internal error.

  1. Turn the power switch off.

  1. Disconnect the intelligent tester from the DLC3.
